THRESHING-MACHINE.

Original application filed July 19, 1915,

To all whom it may concern Be it known that I, HENRY H. Sorrnn'r'rn, acitizen of the United States, and a resident of Napoleon, in the countyof Henry and State of Ohio, have invented a certain new and usefulThreshing-Machine; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to thecharacters of reference marked thereon, which form a part of thisspecification.

This invention relates to grain threshing machines, and particularly tothe grain cleaning and separating means thereof.

The object of my invention is the provision of certain improvements inmachines of the class described whereby to enhance the practicabilityand efiiciency thereof.

The invention is fully described in the following specification, andwhile, in its broader aspect, it is capable of embodiment in numerousforms, a preferred embodiment thereof is illustrated in the accompanyingdrawing which is a central vertical longitudinal section of a portion ofa machine embodying the invention.

This application is a division of the application for patent Serial No.40,659 filed by me in the United States Patent Oflice on July 19, 1915.

Referring to the drawings, 1 represents the frame of the machine whichmay be of any suitable design and construction. Mounted in the rear endof the frame 1 is the customary threshing cylinder 2, which operatesover the concaves 3. Forward of the cylinder 2 is dis-posed theshaker-frames 5 and 6 over which the straw passes in its travel throughthe machine, said frames being mounted in any suitable manner forshaking movements to facilitate an advancing of the straw thereover anda separation of the grain therefrom, as is well understood in the art.

7 is a grain-bottom which extends under the threshing mechanism andshakerframes 5 and 6. The forward and rear ends of the grain-bottom 7are supported for swinging movements longitudinally of the machine bysets of rocker-arms 8 carried by the respective sides of the machineframe 1. A shaft 9, which is journaled trans-.-

Serial No. 59,014.

versely of the machine frame, below the grain-bottom 7, has eccentricrod connection 10 with the rear end portion of the grainbottom, wherebylongitudinal shaking movements are imparted to said bottom by a rotationof the shaft 9. The forward end portion of the grainbottom 7 is provided with a grain-pan 11, and in advance of such grainpan withforwardly projecting fingers 12. A grain-board or bottom 13 isswingingly suspended under the forward end portion of the straw-rack 6to catch grain as it drops through the superposed portion of said rackand to direct it rearwardly to the grain-bottom 7, the member 13terminating at its rear end over the grainpan 11.

A blast-fan 1 1 is located within a circular housing 15 below thecentral portion of the grain-bottom 7 and said housing is provided atits rear side with an upwardly and downwardly extending air inletpassage 16, which is controlled by a wing form of valve 1-7 located, inthe present instance,

.at the upper end of the center partition of the passage. At the lowerforward side of the housing 15 is provided an outlet or blast-passage18, the upper wall 19 of which extends upward and forward and terminatesat its forward end in an upwardly turned flange 20 beneath the grain-pan11 at the rear edge thereof. The bottom wall of the blast-passage 18extends only a short distance from the housing 15 and terminates at itsforward end in a pivoted blast-board 21, which is adjustable to restrictor enlarge the blast-passage 18, as is also a forwardly projectingblast-board 22, which is pivoted to the upper wall of the passage 18 atthe rear or inner edge thereof. A blast-board 23 is disposedintermediate the blast-boards 21 and 22 and is pivoted at its forwardedge as shown. The provision of the adjustable blast boards or gates 21,22 and 23 in the blast-passage 18 in the arrangement shown and describedpermits a perfect control of the air blast through said passage.

24: is a shaker-frame, which is mounted immediately in advance of theair-blast passage 18 and carries a riddle or sieve 25 in position tointercept a portion of the air blast from said passage, provided theblastboards or gates are properly adjusted for that purpose, as shown inthe drawing. The riddle or sieve 25 is preferably pivoted at its forwardend to the shaker-frame 24, as

I the tailing-auger 36 is mounted, as is well at 2.6, and has its rearend in vertically adjustable connect-ion with the shaker-frame throughthe medium of a rack-bar and pinion connection 27, thus enabling therear end of the sieve to be raised or lowered relative to the forward orpivoted end of the blast-board or gate 23. The riddle orsieve 25 has itsrear end portion disposed below the grain-pan 11, whereby grain droppingghrough said pan is deposited on said rid- An inclined divider-board 28for the air blast is fixedly carried by the shaker-frame 24: above therear end portion of the riddle 25 and below the forward end portion ofthegrain-pan l1, and serves to intercept a portion of the grain droppingfrom the grain-pan 11 and to direct it into the rear end portion of theriddle. Pivoted to the forward end of the divider-board 28 is adivider-board 29, which is adjustable to regulate the quantity of theair blast which flows over or under the divider board. A raising of thedivider-board 29 restricts the air passage between the divider-board andforward end of the grain-bottom 13 and causes more grain and coarsematter to flow down the board than would otherwise be the case, and alowering of said boardpermits coarse matter to be blown over the top ofthe board. The shaker-frame 24: is provided below the riddle 25 invertically spaced relation thereto with a rearwardly' declininggrain-bottom 30, which preferably terminates at its rear end slightlybelow the inner end portion of the blast-board or gate 21 and over thecustomary grain-trough 31 in which is mounted the grain-auger 32. Aspace is provided between the forward ends of the riddle 25 and bottom30 to permit the passage of an air blast therebetween.

The shaker-frame 24 is carried for shaking or swinging movementslongitudinally of the machine by two sets of rocker arms 33, which arepivotally suspended from respective sides of the machine frame. 34'extends from the shaker-frame 2 1 and has eccentric connection with theshaft 9 whereby a rotation of said shaft imparts shaking movements tothe shaker-frame.

I The chaff and coarse matter, which is blown from the grain as it dropsfrom the grain-pan 11 onto the riddle 25 and through said riddle to thebottom 30, is blown forward and the heavier particles thereof droppedinto the tailing-trough 35 in which understood in the art.

The bottom of the fanhousing 15 is provided with a shallow blast passage37 V which opens at its rear ends into the body port-ion of the fanchamber and at its forward end over the grain trough 31 in positiontodischarge a blast of air through the A rod .36 are driven in the usualor any desired manner, as is well understood in the art, and asindicated by dotted lines in the drawing.

While I have herein shown and described one specific embodiment of myinvention for illustrative purposes and have disclosed and discussed indetail the construction and arrangement incident to one specificapplication thereof, it is to be understood that the invention is notlimited to the more detail or relative arrangement of the parts, butthat deviations from the illustrated form or embodiment of the inventionmay be made without departing from the spirit of the claims.
